Want an easy way to **** someone off?
Offer them a /duel then as you are about to win, during the slo-mo finishing move animation quickly type:
/duel stop
This will not only give you a free CQ point, but will force them to go back to the loading area instead of just poping back up, hence the name "Dirty-Duel"
NOTE: for even better effectiveness you can go ahead and type it out and wait to press Enter untill the golden moment...
